Abstract

The trend nowadays is towards communication and the way to communicate between the source and destination remotely. This work presents a new technique to communicate among different locations, either automatically or based on notification request. The work methodology was proposed to connect among FOUR different locations and store the data of each individual location periodically. For more applicability, the data chosen to be shared between the four locations are the substantial weather station items identified by (Temperature, Humidity, and Wind speed). Hereby, the tendency is to design robust real time weather station system in order to realize climate conditions at the proposed locations. Finally, the communication module that was chosen to run the system is Arduino microcontroller GSM shield.

Abstract

The recovered sedimentary organic matter from the Tithonian-Berriasian Chia Gara Formation was studied from three selected wells of Ajil-12 (Aj-12), Hamrin-1 (Hr-1), and Tikrit-3 (Tk-3) in Northern Iraq. Amorphous organic matters appeared to be the dominant components of the organic matters within the formation with more than 93%, whereas phytoclasts and palynomorphs comprised only few percentages. As no intensive variations observed in the percentages of the determined organic matters along the studied Chia Gara Formation except a slight increase in phytoclasts and palynomorphs in its uppermost part, therefore the formation considered to be representing only one mainpalynofacies type that subdivided into two secondary palynofacies. Using Tyson's APP ternary, the formation appeared to be deposited in a distal suboxic-anoxic basin. As source rock, the formation in the studied locations contains moderate to very good quantity of organic matters which compose mainly of type II and Type III kerogen (separately or mixed). The whole formation has the ability to generate oil or gas except the upper part of the formation in the location of the well Aj-12 in which less than the lower limit of the required S2 values for considering as source rock is recorded.

Abstract

A layered technique formulation through the depth of reinforced concrete beam section is devoted to develop an incremental-iterative algorithm suitable for the analysis of beams strengthened by CFRP laminates under monotonic and cyclic loading conditions. Concrete nonlinear behavior in compression through loading, unloading, and reloading stages is considered with a tension-stiffening model to represent concrete in tension. A bilinear behavior with strain hardening model of steel reinforcement bars through loading, unloading, and reloading stages is used. A computer program Matlab code is developed and verified through comparisons with given experimental case studies available in literature, which show good agreement. Extending the present algorithm to include different sections, hybrid beams, and long term effects are recommended as future work.

Abstract

The Directorate of Dormitories at the University of Kirkuk offers full accommodated rooms to the male and female students. However, the directorate registers and assigns the accommodations manually. Therefore, a visiting has been made to the directorate to identify the problems of this system. It is found that the manual system suffers from several issues such as wasting time, losing data and extra charges in documenting students' information. Additionally, delays in replying to students’ enquiries, and ignoring their discipline in distributing them among the accommodations. This paper proposes using an e-governance system to tackle the identified problems. The proposed system permits the student to register online and provides him/her with an id card. The id card consists of a serial number, ISBN and student's room information in the accommodation. To design the system, a number of programming languages is used: (PHP, HTML, JAVA SCRIPT and CSS). Furthermore, SPSS software has implemented to evaluate the system. The evaluation has shown significant merits in terms of the reliability and speeding up of assigning rooms to the students among the accommodations. The distribution of the students is according to students discipline. Furthermore, the system determines the capacity of each accommodation precisely. Moreover, decreasing in time wasting and tiredness that may students face in the traditional manual system. Additionally, reducing the physical contact between the students and the employees. Consequently, the proposed system gathers students' information in an electronic archiving which may lead to easiness in importing their information in the future.

Abstract

The present research aimed to evaluate contamination levels of soil by heavy metals. Eight sites were selected for the collection of soil samples. The soil samples analyzed for eight heavy metals namely As, Pb, Cd, Cr, Co, Cu, Ni, and Zn by using ICP-MS technology. The spatial distribution patterns of environmental assessment factors and indices were drawn using Geographic Information Systems (GIS), which is gives understanding for the geographical distribution of contamination levels in the area. The heavy metals contamination assessed by using several environmental factors and indices: Contamination Factor, Degree of Contamination, Pollution load Index, Enrichment Factor, Geo-accumulation Index, Nemerow Index. The environmental factors and indices showed that the soil was moderate to heavily contaminated by studied heavy metals. The EF values indicated that the metals Pb, Cr, Co, Cu, and Zn were enriched from natural sources, while the metals As, Cd, and Ni were enriched from anthropogenic sources.

Abstract

The aim of this paper is to determine the bulk etch rate Vb of the nuclear track detector CR-39 using the method based on measuring the thickness of the layer removed from the surface of the detector (the thickness difference) by the chemical etching, and then studying how to change it with the temperature of the etching solution to extract an empirical relationship between them. The detector samples were etched in a 6 N of NaOH solution at temperatures 80, 70, 60 and 501 oC, and the thickness of the removed layer was determined by successive measuring the detector thickness for etching times of 1-9 h increasing with 1 h intervals. The results showed that the values of Vb range between 2.351-0.605 μm/h for etching temperature 50-80 oC respectively. An exponential relationship was obtained between the bulk etch rate and the etching temperature. It was noted that the results were consistent with that obtained by other studies using the track Length-diameter- (Le-D) measurement method. The slight difference in Vb magnitudes between the compared results is due to the slight difference in the concentration of the etching solution in certain

Abstract

Photovoltaic module surface soiling due to dust deposition is a common problem, especially in the desert environment. In Iraq, Massive dust and sand-storms are environmental phenomena that frequently occurs during the year. Increasing desertification and decreasing vegetation coverage are one of the reasons for the recurrence of this phenomenon. Dust accumulation can reduce the performance of photovoltaic modules output power. This paper investigates the effect of dust accumulation on the performance of PV modules and the possibility of the energy losses experimentally. For this purpose, a microcontroller based dual axes sun tracker is designed and installed at the rooftop of the Engineering faculty Building located at Kirkuk University Kirkuk, Iraq. Two identical PV modules and real-time measurements with data monitoring system are used in this study. This study covers measurements done in August and December (2017). The results showed that the dust deposition on PV module could cause significant losses in PV output power generation on both fixed and sun-tracking modules. However, the losses was less in tracker system.

The results of the evaluation showed the natural accumulation of the Tuz- Chai River sediments, which are geologically belonging to Quaternary deposits and its suitability for use in the road works. This evaluation showed the possibility of the use of the untreated pebbles of the Tuz- Chai River in the road works for sub base layer (type A, B and C). It can also can be used to produce asphalt-fixed gravel and sand for roadwork construction and for asphaltic base layer.
